MACHINE FOR CLEANING- BLINDS, &C.

Specication of Letters Patent No. 10,792, dated April 18, 1854.

To LZZ whom it may concern y Be it known that I, GEO. WV. LA BAW, ofJersey City, in the county of Hudson, State of New Jersey,have inventeda new and useful Machine for Cleaning Doors, Blinds, Shutters, andPanel-iWork Generally that Said Machine can be Applied to.

The present mode of cleaning doors, Blinds, &c., is by hand. First,after the work -is put together it is smoothed o with a plane, so as tobring all the cross rails and stiles to a true surface; 2d, it issmoothed with sand paper rubbed by the hand. By the present mode onehand can clean 12 or 15 doors in about 10 hours, and lighter workproportionally. Such a machine as I now apply for a patent has long beenneeded. The knives or cutters being long enough to reach the `wholewidth of the door, or article to be cleaned, with a straight and smoothedge, will make a truer and smoother surface than can be done by hand,and the sanded cylinder being of the same length and revolving at arapid rate will do the work better and cleaner. I am condent that twooperators can with my machine clean one door in two minutes, or 300 inten hours, and do the work much easier than can be done by hand.

I do hereby declare, that the following is a clear and full descriptionof the construction and operation of the same, reference being had tothe accompanying drawings and letters of reference marked thereon.

Figure 1 is a perspective view of the machine in operation. Fig. 2represents the door or article to be cleaned, dogged on the carriage,and the position of the cut-ters and sanded cylinder, which are placedparallel to each other. Fig. 3 shows the side View of the carriage,feeding, and reversing gearing. Fig. 4c the sanded cylinder. Fig. 5 thewrought iron cylinder, with four knives or cutters attached. i

In Fig. 1 a, a, represents the frame work of the machine; Z9, carriage;c, c, way pieces of carriage, Z), Z2; (Z, bed piece of ditto; e, door orarticle to be cleaned, securely dogged on carriage b, 6, f, f, f, f,stress pulleys on carriage Z), b; g, cover to cylinder with cutters;screw passing through bed piece of carriage Z), Z2, for raising andlowering it; z', pulley on the end of revolving cutters; y', ditto, onthe end of sanded cylinder; Zo, lc, jack shaft; Z, Z, pulleys on the endof same with straps passing over the pulleys i and j; m, pulley forreversing; a, pulley on upright shaft; o, screw gearing; p, lever forthrowing the screw gearing out of gear; g and T, levers for reversingcarriage; s, driv ing pulley on the end of cylinder; o, o, screws forsecuring way pieces.

Fig. 2, represents the door or article to be cleaned, dogged on thecarriage, by the dogs c, c, and showing the position of the revolvingcutter a, and the sanded cylinder ZJ, which are placed at an angle offrom 30 to 60 degrees. Fig. 3, a, door, &c.; s, s, carriage; Z9, cutter;c, sanded cylinder; cZ, d, segments; e, cog wheel working in segments;7c, Zn, jack shaft with 3 pulleys Z, Z, and m, and screw 0,' p, stresspulley; w, an upright shaft; o, a strap over stress pulley.

Fig. 5, is a wrought iron cylinder, with four knives or cutters, showingonly three; a, a knife and cap fastened to cylinder; rib, with knife cand cap CZ taken olf.

The operation of said machine is as follows: The article to be cleanedbeing placed on theV carriage and securely dogged. The wrought ironcylinder a, Fig. 2, is set in motion by the driving pulley s, Fig. l. Astrap placed over the pulley z', on the end of the cylinder, and thepulley Z, on jack shaft, Zr, Zr, causes the shaft to revolve; and thesanded cylinder is revolved by a strap placed over pulley Z, on jackshaft and pulley y', on sanded cylinder. The screw t, on jack shaft 7c,7c, Fig. 3, working in the cog wheel o, Fig. 3, revolves the uprightshaft w; the upper cog wheel e, on this shaft working in the segfoot,will press the stress pulley p, Fig. 3, lThis machine as original, andthe appliagainst the strap fv, Fig. 3, and this Will give cation of it,for cleaning doors, blinds, shuta reversing motion to the shaft fw, andthat ters and panel Work generally.

will move the carriage b, b, Fig. 1, back- GEORGE W. LA BAW.
